A NOVEL MULTIHOP BASED PROTOCOL FOR DEVICE-TO-DEVICE COMMUNICATION FOR COGNITIVE RADIO WITH ONLINE NETWORK DYNAMICS

Abstract

Because it is anticipated that the volume of traffic in networks based on 5G will expand exponentially, efficient techniques are required in order to make the most of the section of the wireless spectrum that is currently underused. The proliferation of different mobile applications over the past several years has led to a large increase in the amount of data traffic carried by cellular networks. Because of this, it is absolutely necessary to expand the capabilities of the network in order to support the introduction of new applications and services. On the other hand, multihop D2D communication necessitates the use of additional nodes for the purpose of data forwarding, and this is especially the case when cooperative relays are included. We need to address the issues of transmission scheduling, routing, and channel allocation in order to realise our goal of achieving effective multi-hop D2D cooperative communication. The system architecture that has been presented places an emphasis, among other things, on using online algorithms to manage network dynamics.
